    Abstract: Die vorliegende Erfindung betrifft ein Verfahren zur Hydrierung von organischen Nitrilen mit Wasserstoff in Gegenwart eines Katalysators in einem Reaktor, wobei der Katalysator als Formkörper in einem Festbett angeordnet ist, dadurch gekennzeichnet, dass der Formkörper bei Kugelform oder Strangform jeweils einen Durchmesser von 3 mm oder weniger, bei Tablettenform eine Höhe von 4 mm oder weniger und bei allen anderen Geometrien jeweils einen Äquivalentdurchmesser L = 1/a' von 0,70 mm oder weniger aufweist, wobei a' die externe Oberfläche per Volumeneinheit (mm s 2 /mm p 3 ) ist, mit: (I) wobei A p die externe Oberfläche des Katalysatorpartikels (mm s 2 ) und V p das Volumen des Katalysatorpartikels (mm p 3 ) ist. Ein weiterer Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von Folgeprodukten von Isophorondiamin (IPDA) bzw. N,N- Dimethylaminopropylamin (DMAPA) aus erfindungsgemäß hergestellten Aminen.

    Abstract: The invention relates to a process for a continuous production of polyetherols comprising the steps of reacting of an alcohol (3) with a starter (5) or an alkoxylated precursor to give a mixture comprising an alcoholate and water, removing the water from the mixture by distillation,if appropriate feeding the alcoholate into a bubble column (23), having an inclination of from 0 to 90 to the horizontal, the bubble column (23)being divided into at least two compartments (25), wherein the compartments (25) are divided from each other by a dividing wall (27), the dividing wall (27) having a height, that liquid can flow over the dividing wall (27) from one compartment (25) into an adjacent compartment, feeding of alkylene oxide into at least one compartment (25) at the bottom of the compartment such that the alkylene oxide rises in the alcoholate, reacting of the alkylene oxide with the alcoholate or a secondary product being formed by the reaction of the alcoholate with alkylene oxide to give the polyetherol, discharging the reaction product from the bubble column (23).

    Abstract translation: 本发明涉及一种连续生产聚醚醚的方法，包括以下步骤：使醇（3）与起始物（5）或烷氧基化前体反应，得到包含醇化物和水的混合物，通过 蒸馏，如果适当地将醇化物进料到气泡塔（23）中，其具有0至90°相对于水平面的倾斜度，气泡塔（23）被分成至少两个室（25），其中隔室（25） 通过分隔壁（27）彼此分开，分隔壁（27）具有高度，液体可以在分隔壁（27）上从一个隔室（25）流到相邻的隔室中，将烯化氧进料到 在室的底部的至少一个隔间（25），使得烯化氧在醇化物中升高，烯化氧与醇化物的反应或通过醇化物与烯化氧的反应形成的次级产物至gi 然后将聚合物从气泡塔（23）排出。
